Importantly, despite their widespread use, the human and wildlife toxicity of herbicides has not been well studied. Evidence suggests that at least some may induce detrimental health effects even at low exposure levels. Importantly, recent molecular studies suggest that glyphosate-based herbicides can impair retinoic acid signaling, producing teratogenic effects. Thus, the finding of human effects consistent with impaired retinoic signaling in agricultural areas with heavy RoundUp use raises concern about the potential health effects of heavy herbicide usage. Although these studies do not prove that RoundUp/glyphosate creates unwarranted human risks, they raise significant concerns. Labeling GMO products would allow consumers to make choices based on these concerns.
